New independent control of a Bi Machine system powered by a multi-leg inverter applied to four in-wheel motor drive electric vehicle

The four-wheel-drive electric vehicle's traction chain is powered by four permanent-magnet synchronous motors (PMSM), a single three-phase, five-leg inverter (FLI). In order to achieve the behavior of mechanical differential and require parallel wheel-motors turn at identical or different speeds, using this structure, an independent control applied on each driving wheel. For particular there shared leg between two phases machines. other machine are attached their own legs. This work's main focus suggestion new DTC technique for vehicle (EV) with set bi-PMSM motor-wheels fed in three-phase inverter. simulation results show that can ensure excellent dynamics system.
